| Abstract |
| This study was performed to fabricate porous titanium foam by three-dimensional layer manufacturing process, and to evaluate the porosities, compressive stress, Young`s modulus and fracture pattern. Porous titanium foam was made of CP(Commercial Pure) titanium powder (≤5 ㎛). Total porosities of titanium foam were in the range of 55-68%. Pore size distribution was 200-440 ㎛ for coarse pores, 50-100 ㎛ for intermediate pores and 5-10 ㎛ for fine pores. Compression elastic modulus and compression stress were decreased with increasing porosity. Young`s modulus ranged from 1.04-5.62 GPa and maximum stress ranged from 20-241 MPa. Regarding the mechanical properties, 3D(Three Demensional) porous titanium fabricated layer manufacturing is a promising material for human bone replacement. |
